BUILDING CONSTRUCTION Filed Feb. 2, 1931 Patented Oct. 4, 1932 UNITED STATES LEOPOLD J. KANTZLER, OF BAY CITY, MICHIGAN BUILDING CONSTRUCTION Application filed February 2, 1931. serial No. 512,872.

The prime object of the invention is to design a' rigid, fireproof and inexpensivestud for use in fireproof buildings, which can be readily formed to shape, and to which metal :1 lath, plaster board, or other building material can be readily secured.

Another object is to provide a stud having a. wood core or nailing section into which nails can be driven, and which will anchor and hold the nails the same as the conventional wood studding at present in general use.

A further object is to provide a rigid, fireproof stud which will be light in weight, easy to handle, and of simple and practical construction.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanyin drawing, and particularly pointed out in t e appended claims, it being understood that changes ma be made in the form, size, proportion an minor details of construction, without de arting from the spirit or sacrificing any 0 the advantages of the invention.

In the drawing: a Fig. 1 is a fragmentary view showing my improved studding in place in a wall, with a sheet of composition board nailed thereto.

Fig. 2 is an enlarged perspective view of one of the studs.

Fi 3 is a transverse sectional'view showe nail driven into the core. ferring now more articularly to the drawing in which I have s own the preferred embodiment of my invention, the stud is designed foruse in the conventional manner, and is composed of identically similar plates 5 and 6 respectively, preferably shaped as clearly shown in Figs. 2 and 3 of the drawing, the edges of each plate being bent at right angles to the main body, and forming flanges 7 against which the lath, lumber, or composition wall board 8 is secured.

These plates are secured together in spaced apart relation, and wood members 9 and 10 respectively form cores or fillers as shown,-

" the outer edges of the plates being Welded together at spaced apart points 11so that a umtary, one-piece stud is secured. The plates are shaped so that the fillers 9 can be cut to best advantage and with economy, and the spacing A between plates is suflicient to accommodate a nail 12 which is driven into the core 9 in the same manner that materials are nailed to wood studs at present in general use. I

The center sections of the plates are also welded together at spaced apart points 13, as the core is composed of two separate wood strips slightly spaced apart, or any other suitable composition may be used, this core prevents buckling, reinforces the stud, supplies the nailing strip, and is easy and economical to make, inasmuch as the core is con fined by the metal side plates, it is immaterial whether it splits or cracks, and any crack will be limited, due to the fact that the core snugly fits the shell formed by the plates. It is of course obvious that. this same construction may be used for joists, lintels, or in fact may be used as any structural member of a building.

The plates are a rolling operation, insuring mass production at a minimum cost, and are rolled to the length required, eliminating wastage, the assembly is very simple, there is no shrinkage to contend with, and a building in which these studs are used will develop no unsightly cracks as occurs whenwood studding is used.

What I claim is:

1. A metallic studding comprising a pair of formed sheet metal members welded together in spaced apart relation at the center and edges, and shaped to receive two individual wood filler members, the edges of said filler members being tapered and spaced inwardly from the edge of the sheet metal members, the spacing of said members at their edges being sufficient to permit nails to be driven into said filler members.

. 2. A metallic studding comprising a pair of formed sheet metal members, the outer edges of which are bent at right angles to the main body to form flanges, a filler member interposed between said members and formed with reduce v dnres spaced inwardly from said flanges, and to which metal members eonform, the metal members being welded together at a point adjacent the flanges, and bein spaced to permit nails being driven into sai filler member.

3. A metallic studding comprising a pair of formed sheet metal members, the outer edges of which are bent at right angles to the main body to form flanges, a filler member interposed between said members, the

edges of said filler being reduced and spaced inwardly from said flanges, spaced apart raised sections adjacent the flan es to permit the metal members being wel ed together, the spacing at the edges of the members being suflicient to permit nails being driven into said filler.

In testimony whereof I hereunto afiix my signature.

LEOPOLD J. KANTZLER.
